Abstract

A multilayer bag filter element for milk purification, made in the form of a sleeve with a blind end, and the sleeve walls are multilayer of food-grade polymer by the method of thermodynamic extrusion, by means of which the polymer filaments are welded to each other during winding to form stiff layers with conducting channels, and equipped with a transition adapter in the form of a washer with a fitting in communication with the outlet and having an external thread for tight fastening on it the free end of the sleeve.

Description

The utility model relates to filtering technology in the food industry, namely, to liquid filtration devices, mainly milk.

Currently, in the production / processing of milk for its purification in milk pipelines, both domestic and imported, single-layer filter elements of the bag type are used (see, for example, http://centr-np.ru/catalog/70/71/ ? 12.0 or http://rustm.net/catalog/article/186.html). The disadvantages of such filter elements are low strength, low throughput, rapid contamination and, as a result, the need to replace the filter elements during milking, the difficulty of replacing the filter elements, as well as the filter element, can break and all the dirt gets into milk.

The prior art discloses a multilayer filter element devoid of these drawbacks for the fine purification of raw milk, made in the form of a tubular cartridge made of food-grade polymer material, formed by discrete rows of fibers obtained by aerodynamic extrusion with radially decreasing pore sizes from the periphery to the center, each row consisting of of frame and filter fibers, and the thickness of the filter fibers is greater than the frame (see patent RU No. 2429897, CL B01D 27/00, publ. 09/27/2011). However, such a filter element can only be used in a special filter housing.

The objective of the utility model is to eliminate the shortcomings of the filter elements and create a universal bag filter element that can be used on any milking installations without purchasing a special filter housing.

The technical result consists in increasing the efficiency of the use of the filter element by increasing the throughput compared to bag filter elements, simplifying the design that does not require laborious work on commissioning, installation and dismantling, as well as the possibility of using the filter element with any type of milking equipment. The problem is solved, and the technical result is achieved by the fact that the bag-shaped multilayer filtering element for milk purification is made in the form of a sleeve with a blind end, and the walls of the sleeve are made of food-grade multilayer using thermodynamic extrusion method, by means of which the polymer threads are welded one to one to ensure rigidity another with the formation of discrete layers with conductive channels and is equipped with a transition adapter in the form of a washer with a fitting in communication with the output and having an external thread for flat mounting on it the free end of the sleeve.

Figure 1 shows a cross section of a filter element;

in FIG. 2 - assembly drawing.

The multilayer filter bag for milk purification is made in the form of a sleeve 1 with a blind end 2. The walls of the sleeve are made of food-grade polymer (polypropylene) by thermodynamic extrusion, by means of which the polymer threads are welded to each other in the winding process to form stiffness with the formation of discrete layers with a huge number of conductive channels. At the free end of the sleeve 1, an adapter is installed in the form of a washer 4 with a fitting 5 connected to the outlet and having an external thread for tightly fastening the free end of the sleeve 1 on it. The filter element through the adapter is suitable for almost all existing cases of devices for cleaning milk from all existing milking systems without any alteration or refinement. In FIG. 2, the housing 6 of the milk purification device is equipped with an inlet pipe 7 on one side and a flange 8 with an external thread on the other. On the output side there is a lid 9 with an internal thread connected threadedly to the housing 6 and the outlet pipe 10. The adapter adapter 4 is sandwiched between the inner surface of the lid 9 and the end face of the housing flange 8. On the mating surfaces of the adapter adapter installed in the annular grooves of the sealing ring 11.

Milk under pressure enters the inlet pipe 7, passes through the filter element into the sleeve 1 and, in purified form, is discharged into the outlet pipe. Thanks to the multilayer porous structure, milk passes through the sleeve without hindrance even when heavily soiled, while the high throughput allows it not to be changed during milking (the traditional bag filter is designed for an average of 300 liters of milk, and the multilayer bag filter element is designed for 1 milking). The size of the multilayer filter element depends on the amount of milk per 1 milking.

The absence of springs when installing a multilayer bag filter element allows you to quickly replace the filter element, and the presence of the adapter allows you to use it with milking equipment of any type.
